SASH RAISING .AND FSTNING MECHANISM.

Application :filed May 19, 1922. Serial N0. 562,073.

To all 07mm it 01mg/ concern:

Be it known that we, ARTHUR DANIEL RawLrNGs and Ennnsr .l'oHN RAwL1NGs,sub jects of the King of Great Britain, residing at London, England, have invented certain new and useful Imp\rovements in Sash Raising and Fastening Mechanism, of which the following is a full, clear, and exact description.

This invention relates to improvements in automatic sash raising mechanism and more particularly to improvements in the construction shown in Rawlings and Rawlings Patents, Nos. 1,154,432 and 1,364,887, and application, Ser. No. 422,344, filed Nov. 6, 1920. in the prior patents and application re,- ferred to an automatic sash raising and controlling mechanism was shown and de# scribed, which was adapted to permitl the automatic raising of asash or the locking of the same in any desired position.

The present application is directed in general to a simplification of the construction and the provision of an improved lock for securing the sash in any desired position.

Further objects and advantages will be hereinafter set forth in the accompanying specification. y 4

In. the drawings:

Fig. 1 shows, by way of illustration, the improved mechanism applied to an automobile door.

Fig. 2 shows a detail sectional view taken on line 2v2 of Fig. 3.

Figs. 3 and 4 show detail views of the locking mechanism and are taken on lines 3-3 of Fig. 1. These figures show the lockingparts in locked and unlocked position.

igs. 5, 6 and 7 are detail views of the locking knob and are sectional views taken on lines 5-5, 6 6 and 7*7 of Figs. 3 and 4.

Fig. 8 is a detail sectional view o-f a modi- Vication.

Referring to Fig. l, 1() is a case which contains a spring actuated roller mechanism 11 preferably of the type shown in our Patent No. 1,154,432. This raising7 mechanism is provided with the usual fusee wheels 12 which have cords thereon extending to a suitable carrier 13 for the glass window 14. Lowering of the window is effected by means of the usual pull cord 15. The glass pane is mounted in any desired manner for vertical sliding` movement in the frame 16 and is here shown without stiles, although such members could be used, if desired.

The case containing the raising mechanism is preferably mounted to be movable in and out relatively to the frame and in the embodiment shown in Fig. 1 this is secured by providing a suitable pair of arms 17 which are pivoted at their upper ends at 18 to the frame and which, at their lower ends, are suitably connected tothe case 10. The pivoted arms 17 are preferably provided with suitable friction strips 19 which engage the glass or sash when the arms are swung vinward and lock the sash in adjusted po sition. When the arms are away from the sash the latter is free to be moved up or down under the control vof the pull cord or raising mechanism.

With devices of this sort, particularly when used on automobiles and the like which are subject to vibration, it is desirable that some'positive means be provided for locking the window. Such locking devices should be on the interior of the door `and should prevent unauthorized opening of the window from the outside when the door is locked. Accordingly, the mechanismshown in Figs. 3 to 7 is provided. Suitably concealed within the frame and preferably below and in front of the case 10 are a pair of centrally pivoted levers 20, each having a pin connec tion 21 with the case 10. Each lever through asuitable stud 22 is connected to a controlling block 23 which is interiorly` threaded to receive a threaded shaft 24. The shaft 24 is carried by a stud or plain shaft 25 which, at its inner end, carries a suitable knob 26. The shaft 24 is provided with a key portion 27 which is adapted 'to pass through a suitable slot 23 in t-he bearing 29 when the shaft is turned to the position shown in Fig. 6.- ln this position the shaft may be displaced bodily to the left to rock the levers 20 from the position shown in F ig.` 3 to t-he position shown in Fig. 4. lVhen in the latter position the levers will have swung the raising mechanism inwardly and released the sash engaging arms.

By drawing the knob outwardly when in the position shown in Fig. 6, the levers may be displaced in reverse direction. Then, by

turning the knob clockwise the key portion 27 will come into cooperation with a cam edge 30 and effect further displacement of the shaft to the right to the position shown in Fig. 5. During this bodily displacement of the shaft, its rotation displaces the block on the threaded portion and thereby imparts an additional clamping pressure to the locking lovers 20.

The locking device has the capability of being quickly unlocked by turning the knob counterclockvvise and then pressing inwardly upon it. By a reverse operation the window may be clamped both rapidly and firmly.

In the embodiment shown in Fig. 8, the sash` engaging arms are omitted` and. the friction strips are directly mounted upon the rear of the case l0 at the edges thereof. The, case is here shown as mounted for a slidable in and out movement relatively to the frame 16. This embodiment of the invention finds particular utility in` applications to automobiles of the cabriolet type in which the frame members do not: extend any substantial distance above the sill and accordingly do not permit the provision of pivoted sash enga-ging means of the type heretofore described.

What I claim is:

l. In a device of the class described in combination a sash, an automatic raising mechanism therefor, and locking devices for said sash comprising sash engaging means and manually operable multiple ratio devices for operating the same to engage or disengage the sash.

2. In a device of the class described in combination a sash, an automatic raising mechanism therefor, and locking devices to maintainv the sash in any adjusted position or release the same, said devices comprising apair of pivoted levers. a knob operably connected therewith and displaceable inwardly and outwardly, and cam devices for retaining said knob in manually adjusted position.

3. Inl a device of the class described, in combination with a sash raising mechanism mounted for in and out movement in a frame, a sash engaging means displaceable concurrently with said raising means, a pair of levers connect-ed with said raising means for displacing the same, and a manually operable member for actuating said levers.

t. In a device of the class described, in combinationwith a sash raising mechanism mounted for in and out movement in a frame, a sash engaging means displaceable concurrently with said raising means, a pair of levers connected with said raising means for displacing the same, and a. manually operable member with provisions for actuating the said levers by multiple ratio connections.

5. In a crevice of the class described, in combination with a sash raising mechanism mounted for in and out movement in a frame, of sash engaging means displaceable concurrently therewith into and out of contact with the glass or sash portion, and means for manually displacing said` mechanism and' sash engaging means in both direc tions for the purpose described.

' 6. In a device of the class described, in combination with a sash raising mechanism mounted for in and out movement in a frame, of. sash engaging means displaceable concurrently therewith, and manually oper-i able means for displacing said mechanism and sash engaging means, said manually operable means includingsupplemental devices for exerting a powerful clamping pressure upon said sashby said engaging means.

In testimony whereof we hereto affix our signatures.
